CNC Machine Operator I

CNC Machine Operators operate computer-controlled machines to perform one or more machine functions required to produce customer orders. Skilled Machine Operators are critical to our success, and the reliability and accuracy of our operators is essential. Operators work under varying degrees of supervision to perform simple and complex machining operations, and with development and demonstrated mastery of additional skills and training, operators can advance along our machining career track.
